Unfortunately you'll have to pay again but it's still cheaper than a new transmission. This time when they flush shift through all your positions and Rev a bit.

When doing so, make sure the transmission fluid is at operating temp, and with the car running and in Park, check the transmission dip stick....
with my tranny, I also use Lucas Oil Transmission fluid conditioner: http://lucasoil.com/products/problem-so ... onditioner
I've used this stuff on all of my cars after performing tranny fluid changes....I'm almost nearing 150K on my M....

Nissan sent out a TSB in 2010 not to preform flushes on any of their cars, and Infiniti has it as well. Plenty of Armadas and Titans, and G's and M's transmissions had to be replaced by Nissan of North America because of this. The flush of the trans would cause any material and shavings from inside the trans to be clogged up inside the valvebody, and since Nissan in all of its infinite wisdom decided a long time ago to marry the valve body to the TCU and ECU, that is why you can't use the valve body of an identical model car or valve body from a different same trans to your current car. They immediately sent out a memo to stop doing flushes instead preform fluid transfers. Now if your receipt says transmission flush you can win the argument and contact Nissan of North America and have them handle it, but if it says trans fluid drop and fill or fluid transfer or something to that affect, and no mention of flush then you have a hard case. But I am willing to bet that this dealership did the power flush since your transmission is acting up now. Good luck.

That's the only TSB for ATF I found...Infiniti-TechInfo.com wrote:Special Automatic Transmission Fluid Requirement
Summary of ITB08022:
If Warranty repairs are being done on a transmission listed in the chart below, the listed fluid must be used. A claim to Infiniti for warranty, service contract, or goodwill repairs to the transmissions listed below may be denied if Genuine Nissan ATFFluid is not used as specified by the part # in this bulletin.

It is actually every 60k miles per the book. It also lists flush as an optional service, vs just replacing the fluid which is required by the book at 60k miles.svard75 wrote:If this was the first time a flush was performed on the vehicle since new then it missed 2 flushes by now. I believe it's every 40k miles. Think about how how badly overused the oil would be by the time you perform the flush. Then flush connects to the transmission cooling lines inlet and outlet and they are supposed to run the car while the machine pumps fresh oil in and extracts the old oil out. If the oil has never been changed before the oil filter must be replaced and the magnets cleaned. Performing this process requires them to perform again if the fluids are not completely clean once done. If they used a fluid exchange unit they can watch the color of the fluid coming out but again if it was never performed the filter may be slowly releasing clumped oil and microscopic derbis back into the valve body blocking the oil from properly applying pressure to the band's. I've read many transmission failures are related to clogged valves and symptoms begin similarly to what you described. Of course worst case the electronics or solenoids may have also failed but I'm thinking try the cheaper stuff first.
I agree that this is probably an anomaly. Someone showed up a couple weeks ago saying there is a TSB that says not to flush, but no one has verified the TSB exists. I have a 3rd party mechanic who I recently had do all major services that I do at 60K intervals to my car. For the record, I did a pan drop 30K and 60K miles ago (because this mechanic didn't have a flush machine at that time, my last flush was at the dealership 90K miles ago). My car already had over 170K miles on it at this time, and I mentioned the concern about the transmission flush. The person I spoke with confirmed that their machine connected the way several people in this forum and thread say flushes should occur and only changed out the transmission fluid. He also stated that he had only ever seen a transmission flush appear to cause major problems when there were already minor problems before the flush. Also keep in mind that the OP didn't even have a flush and is apparently having problems after a pan drop.mexillis wrote:hmmm I did the flush at 60k, Im now at 120k wondering if i should drain and fill only or if this is just an anomaly with the service done at this dealership, with that tech, ect. OP let us know what happens. Maybe this is an X thing too? So far based on the forum this is the first "problem" Ive seen posted.
That would be me Dustin! I stand corrected, it was not a TSB, it was a PSB (Parts & Service Bulletin # NPSB/07-027 Dec. 10, 2007) I go through so many of these things I forget if they are published as SIB's, TSB's SIL's or PSB's!The00Dustin wrote:hmmm......Someone showed up a couple weeks ago saying there is a TSB that says not to flush, but no one has verified the TSB exists.......
Sounds like you may have overfilled it, and that's very destructive. There are plenty of threads in here about the right way to get the right level, but in a nutshell, always put in about a quart less than the rated capacity (usually around 5 qts, so you put in 4), then warm the car up fully with several miles of gentle driving, then top up the fluid. Serious overfilling can kill any CVT in under 1000 miles.mohammad wrote: ↑Fri Apr 09, 2021 10:12 amI change the transmission fluid (Lucas CVT fluid!) for my Rogue 2012 AWD and now I am hearing squealing noise at low RPM. The fluid was completely dark and that's why I changed it. Should I do a flush instead? Any comment on this?
I also tried to check the trans fluid while idling. should the fluid be at a higher level in comparison to the condition that the car is not running?
